Specicaton of Letters Patent.

Patented July l9, 1918,

Application led August 15, 1917. Serial No. 186,427.

T0 all 'whom t may concern:

Be it known that we, CHARLEY VINCENT a-nd ALFRED FONTAINE, citizens of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented `certain new and vuseful .,Improvements in Wrenches, of

mounted adjusting rod, engageable witha dogV pivotally mounted in the relatively movable ja w,.andv means for releasing the dog from the threads of the rod to secure the quick adjustment, the liney adjustment being secured by yrotating the rod in the shank, and means being provided for conveniently locking the parts after the desiredy adjustment has been effected..

And the invention also aims to generally i.

improve devices of this class so as to render them more useful andv commercially desirable.

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the different parts that we shall hereinafter more fully describe and claim.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which- Figure 1 is a side elevation of a wrench embodying the improvements of our invention,

Fig. 2 is a longitudinal sectional view thereof with parts in side elevation,

Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 2.

Fig. 4 is a similar view yon the line 4 4 of Fig. 2.

Corresponding and like parts are referred to in the fellewng description and accom,

p'anying drawing by lik reference characters.

Referring to the drawing, the numeral l designates the relatively stationary jaw 'of our improved wrench, and 2 designates the shank to which the jaw 1 is fixed and with which it is preferably integrally formed. Preferably 1the shank 2 is formed on one side face with linear graduations, as clearly illustrated `in vthe drawing.

The shanky2 is formed with a longitudinal bore 'or opening 3 terminating at one end in a socket 4 and communicating with a longitudinal recess or slot 5 formed on one edge of the shank, as shown. A threaded rod 6 is rotatably mounted in the bore 3 of the shank 2 and provided at one end with a trunnion 7 which is mounted in the socket 4, said rod being secured to or formed integrally with a handle 8 and provided, near said handle, with an annular groove 9.

A collar l0 isrmount'ed 'upon one end of the shank 2 and is provided with an inwardly projecting tongue 11 fitting within thezslot 5 of the shank, said tongue havingy a transversely extending lug 12 formed thereon and fitting within the groove 9 of thel threaded adjusting rod 6 whereby, after the collar is slipped upon the rod and upon the shank and secured to the latter, the parts will bev heldin lassembled `relation and the rod mounted to rotate about its longitudinal axis.

13 designates the relatively movable jaw of the wrench formed with a yoke 14 by which it is mounted to slide on the shank 2, j

and said jaw 13 has a dog 15 pivotally mounted therein, one end of the dog being threaded for engagement with the threads of the rodG, as indicated at 16. A spring-encircled rod 17 is carried by the jaw 13 and engages the relatively free end of the dog 15 whereby it is urged into engagement with the threads of the rod 6, and in order to release the dog from the rod whereby a quick adjustment may be secured, we have provided pivotally mounted spring-pressed detent 18 which extends transversely through the jaw 13 to bear against the dog. An end portion of the detent 18 extends exteriorly of the jaw 13 through a side thereof and is so arranged that by moving the detent 18 in one direction, the dog 15 may be swung outr of engagement with the threaded rod 6. Upon releasing the detent the springs 19 theregf will act as well as the sprjfuqlgencir-- cled rod 17, causing the dog to engage with the threads on the rod 6.

From the foregoing description in con-V nection with the accompanying drawing, the operation of our improved quick adjustment wrench will V.be apparent. Y In the practical.

. use of the device, by actuating the detent in engagement with the dog 15.

Preferably the handle 8 is formed in one end with a circumferentially extending sei'ies of longitudinal notches or recesses 20,

and the collar 10 carries a slideV or catch 21` designed to engage inlany `of theJ Arecesses 20, and thus lock the parts from movement.

While the accompanying drawing illustrates what we believe to be thev preferred embodiment of our invention, it is to be understood that the invention is not'limited thereto, lbut that various changesmay be made in the construction, arrangements and proportions of the parts without departing from the scope of the inventionas claimed.

What is claimed, is: Y l 1. A Wrench of the character described,

comprising a relatively fixed jaw,a shank connected thereto, said shank being formed with a longitudinal bore and in one edge with a longitudinal slot Ycommunicating with the bore, a threaded rod rotatably mountedrin said bore, a handle connected to one end of said rod, a collar fitting over one endvof the shank and formedwith an inwardly projecting tongue engaging in v said slot and formed with afrlng, the rod being formed with an `annular groove in which said lug is engaged, a movable jaw slidingly mounted on the shank and pro-V vided with a pivoted dog engageable with the threads of thejrod, the handle being formed in onel end with a plurality of recesses, and a catch Carried by the collar and engageable in any one of said recesses, for the purposespecified.

Q. A wrench of' the character described,

comprising arrelatively fixed jaw, a.' shank connected thereto, saidshank being formed with alongitudinal bore and in one edge with a longitudinal slot communicating with theboie, athreaded rod rotatably mounted in said bore, a handle connected to onefend ,c of saidV rod, a collar fitting overone end ofl theshank and Vformed with anV inwardly projecting ktongue engaging in said slot and formed with a lug, thexrodV being formedY withan annular groove in which said lug c, is engagedy'a movable jaw slidingly mount-v ed onthe shank and provided with a pivJl oted dog engageable with the threads'of the rod, and coacting means carried by the collar and handle for holding the rodagainst Witnesses: y l
